welding outside recommended parameters

04-14-2013, 06:58 AM

What type of weld quality issues will I see if I weld outside the ranges in the manual or the on the door of my Millermatic. Specifically, 'I'm looking for what problems I can expect when trying to weld 24 ga. sheet with 0.024 solid wire and CO2 shielding?

two things can happen, one , it will run like crap, and two, it will be from ok to good, those door charts are starting points. some thing that i never hear on this forum is the need to change settings due to temperature, time of day, ect, in some locations, the juice from the pole will vary, on hot days, it can be low, air conditioners are running ever where, so the wire speed may need to be lowered, or on nights and weekends when there is little industrial use, the line voltage may be higher, causing you to raise your wire speed
